Not really, A lot of nurses either do a lot of nothing or a lot something they have expertise in. Which is why you have some who only train in phlebotomy, or others who just want to prescribe drugs (Nurse Practitioner). Here's what the show conveniently left out; Many nurses work the desk, more than they do anything else. You can see this for yourself, enter a hospital, and walk around for a while, you'll notice there's a lot of nothing being done by the desk jockeys, and usually one older nurse will handle the rounds and call in for some assistance every one in a while. Waiting for someone in Emergency was never more horrifying, seeing how not one nurse took her job seriously.
